Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? MERGE exists and is an alternate of. The shell is the part of the operating system that the user interacts with, and is arguably the most important part of the operating system.

Files can be created, renamed, moved and read from the shell. Computer hardware can be installed, used and removed through the shells. Program applications and scripting can be written, compiled, and ran through the shell. The a default Unix shell is the shell that comes with and is activated initially with your distribution of Unix.

The shell is essentially the program the runs the command line interface allowing someone to interact with their computer. Some examples are the Bourne-Again shell bash or the Bourne shell sh. C shell programming language through Unix?

A little archaic though. I use Ubuntu and Fedora. I think they have 7 out now. They are both free and you can try them with a live CD without having to install anything. You can even keep your windoze OS if you want.

The only reason I still keep win around is for the printer driver. Has to have a propritary microslop driver. Just Google ubuntu and fedora red hat. Answer You can use C-shell csh, tcsh in Unix, and you can write scripts or programs for it.

What are the different shells in Unix? There are many possible Unix shells that users have access to. Some of these are: Unix has two main sets internal implementation and the interface that is seen and used by users. Kernal takes care of hardware interface and shell communicates with Kernal.

Shell works as interpreter of user commands and translates them into action. The shell forms the outer part of the operating system and forms the interface between the user and the kernel.

For each user logged in, there is shell in action. When a command is given by the user, it is examined by the shell and communicated to the kernel for execution.

The functions used to communicate with the kernel are called system calls and are built into the kernel. The system calls are in all the flavors of UNIX are the same.

External commands are saved in file system, when you enter such commands shell searches for them and runs them in new sub-process. Shell is a program which allows the user to access the computer system.

Shell is an interface between the user and computer system. Kernel is the only way through which the programs all programs including shell can access the hardware.

Important Unix Commands

Its a layer between the appliation programs and hardware. It is the core of most of the operating systems and manages everything including the communication between the hardware and software. It contain modules like device modules and other modules etc. Kernel is written in C language.

Basically kernel is mediator between hardware and Operating System. Both are mediator but work is totally different. Let we have an example of "eject" command in Linux operating system:UNIX is important because it changed everything, and it's still changing everything.
